Radon Testing Services
KCI Job # 12146341.29
Location:
Travilah Elementary School
13801 DuFief Mill Road
North Potomac, Maryland 20878
Dear Mr. Cox:
KCI Technologies, Inc. (KCI) is pleased to submit the following report to the Montgomery County Public
Schools (MCPS) pursuant to completing a “short-term” 3 day radon test for the Travilah Elementary
School, located at 13801 DuFief Mill Road in North Potomac, Maryland 20878 (subject site).
Scope of Services:
KCI conducted radon testing at the subject site to evaluate indoor radon levels relative to the USEPA's
recommended action level of 4.0 picocuries per Liter (pCi/L) - the level at which EPA recommends that
schools take action to reduce the level. KCI conducted the radon testing in accordance with American
Association of Radon Scientists and Technologists (AARST) Protocol for Conducting Measurements of
Radon and Radon Decay Products in Schools and Large Buildings. A National Radon Safety Board
(NRSB) Radon Measurement Specialist (certification #14SS056) supervised the testing. Additional
information on radon management and the health effects of radon exposure is available from
www.montgomerycountymd.gov/dep/air/radon or www.epa.gov/radon.
KCI visited the site on February 22, 2016 and deployed fifteen (15) activated charcoal (AC) radon test
kits. KCI deployed radon test kits in frequently-occupied ground contact rooms, and other areas, (if
applicable) in accordance with AARST guidance. A floor plan map of the building with the test locations
is included as Attachment A of this report.
As a quality control measure, KCI included duplicate samples, field blanks, lab transit blanks, and office
blanks in accordance with AARST recommendations. In addition, KCI submitted six (6) test kits to
Bowser-Morner, Inc. as spike samples. The spiked tests were exposed to a known radon concentration by
Bowser-Morner prior to being returned to the laboratory for analysis.
KCI returned to the site on February 25, 2016 to retrieve the radon sampling test kits. KCI shipped all
radon tests via overnight delivery to Airchek, Inc. for analysis by gamma-ray spectroscopy. Airchek, Inc.
is a NRSB certified analytical laboratory for radon analysis (certification # ARL1402) located at 1936

Evaluation of Testing Conditions:
The operating condition that represents the greatest amount of significantly occupied time for this
building is; heating active, with outdoor temperature averages ≤ 65° F.
KCI concludes that the test period reasonably represents normal conditions when the building is
significantly occupied. Clear characterization of the radon hazard is most likely to be observed under this
normal operating condition. Based on the evaluation of test conditions, this test should reasonably
characterize radon hazards.
KCI also conducted observations of field conditions which could affect the results of the test and
compiled weather data for the testing period. Note that strong storms and heavy rainfall were recorded
during the test period. The unusual weather conditions may have resulted in atypical radon test results for
this facility.
KCI recorded observations of the following conditions in each room at the time of deployment and
collection of the radon test kits:
•
•
•
•
•
•
Indoor temperature,
HVAC Operation,
Dehumidifier operation,
Humidifier operation,
Ceiling fan operation, and
Open windows or doors.
Results:
The results of the radon test analysis indicated the following:
Radon Concentration

<4.0 piC/L

See Attachment B
Notes:
D- Duplicate sample
The field blank, office blanks, and lab transit blanks had test results of less than the laboratory detection
limit of 0.3 pCi/L. Review of the duplicate sample analysis indicates that adequate laboratory
measurement precision was achieved. The Spike sample analysis results indicate the laboratory is
operating within statistical control limits.
The sampling locations, field observations, and analytical results are listed on Table 1 (Attachment B).
The laboratory analytical results are also attached (Attachment C). Laboratory results and exposure data
for the spike samples are also included in Attachment C.

Note: Spike samples are test canisters that are deliberately exposed to a controlled high level of radon in a laboratory.
They provide a quality control measure in the testing process and do NOT reflect radon levels in the building being
tested.

Radon Testing Services
KCI Job # 12146341.22
Location:
Travilah Elementary School
13801 Dufief Mill Road
North Potomac, Maryland 20878
Dear Mr. Cox:
KCI Technologies, Inc. (KCI) is pleased to submit the following report to the Montgomery County Public
Schools (MCPS) pursuant to completing a “short-term” 3 day radon test for the Travilah Elementary
School, located at 13801 Dufief Mill Road in North Potomac, Maryland 20878 (subject site).
Scope of Services:
KCI conducted radon testing at the subject site to evaluate indoor radon levels relative to the USEPA's
recommended action level of 4.0 picocuries per Liter (pCi/L) - the level at which EPA recommends that
schools take action to reduce the level. KCI conducted the radon testing in accordance with American
Association of Radon Scientists and Technologists (AARST) Protocol for Conducting Measurements of
Radon and Radon Decay Products in Schools and Large Buildings. A National Radon Safety Board
(NRSB) Radon Measurement Specialist (certification #14SS056) supervised the testing. Additional
information on radon management and the health effects of radon exposure is available from
www.montgomerycountymd.gov/dep/air/radon or www.epa.gov/radon.
KCI visited the site on January 4, 2016 and deployed sixty-six (66) activated charcoal (AC) radon test
kits. KCI deployed radon test kits in frequently-occupied ground contact rooms, and other areas, (if
applicable) in accordance with AARST guidance. A floor plan map of the building with the test locations
is included as Attachment A of this report.
As a quality control measure, KCI included duplicate samples, field blanks, lab transit blanks, and office
blanks in accordance with AARST recommendations. In addition, KCI submitted six (6) test kits to
Bowser-Morner, Inc. as spike samples. The spiked tests were exposed to a known radon concentration by
Bowser-Morner prior to being returned to the laboratory for analysis.
KCI returned to the site on January 7, 2016 to retrieve the radon sampling test kits. KCI shipped all radon
tests via overnight delivery to Airchek, Inc. for analysis by gamma-ray spectroscopy. Airchek, Inc. is a
NRSB certified analytical laboratory for radon analysis (certification # ARL1402) located at 1936 Butler

Evaluation of Testing Conditions:
The operating condition that represents the greatest amount of significantly occupied time for this
building is; heating active, with outdoor temperature averages ≤ 65° F.
KCI concludes that the test period reasonably represents normal conditions when the building is
significantly occupied. Clear characterization of the radon hazard is most likely to be observed under this
normal operating condition. Based on the evaluation of test conditions, this test should reasonably
characterize radon hazards.
KCI also conducted observations of field conditions which could affect the results of the test and
compiled weather data for the testing period. KCI recorded observations of the following conditions in
each room at the time of deployment and collection of the radon test kits:






Indoor temperature,
HVAC Operation,
Dehumidifier operation,
Humidifier operation,
Ceiling fan operation, and
Open windows or doors.
Results:
The results of the radon test analysis indicated the following:

4.3
See Attachment B
<4.0 piC/L
Notes:
D- Duplicate sample
All field blanks, office blanks, and lab transit blanks had test results of less than the laboratory detection
limit of 0.3 pCi/L. Review of the duplicate sample analysis indicates that adequate laboratory
measurement precision was achieved. The Spike sample analysis results indicate the laboratory is
operating within statistical control limits.
The sampling locations, field observations, and analytical results are listed on Table 1 (Attachment B).
The laboratory analytical results are also attached (Attachment C). Laboratory results and exposure data
for the spike samples are also included in Attachment C.
Our professional services have been performed in accordance with customary principles and practices in
the field of industrial hygiene and engineering. If you have any questions or comments regarding this
report, please feel free to contact me at (410) 316-7800.

Note: Spike samples are test canisters that are deliberately exposed to a controlled high level of radon in a laboratory.
They provide a quality control measure in the testing process and do NOT reflect radon levels in the building being
tested.
